background

(Field)
The following description relates generally to wireless communications, and more specifically to managing access control to closed subscriber groups (CSG) cells in a wireless communication environment.

(background)
Wireless communication systems are widely deployed to provide various types of communication content such as voice, data, and the like. A typical wireless communication system may be a multiple access system that can support communication with multiple users by sharing available system resources (eg, bandwidth and transmission power,...). it can. Examples of such multiple access systems include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, and the like Things can be included. In addition, the system may include specifications such as 3rd Generation Partnership Project (3GPP), 3GPP Long Term Evolution (LTE), Ultra Mobile Broadband (UMB), and / or Optimized Evolution Data (EV-DO). Such as multi-carrier radio specifications, one or more revised versions thereof, and the like.

  In general, a wireless multiple-access communication system can simultaneously support communication for a plurality of user equipments (UE (user equipment)). Each UE may communicate with one or more base stations via transmissions on forward and reverse links. The forward link (or downlink) refers to the communication link from the base station to the UE, and the reverse link (or uplink) refers to the communication link from the UE to the base station. In addition, the communication link between the UE and the base station is established via a single input single output (SISO) system, a multiple input single output (MISO) system, a multiple input multiple output (MIMO) system, etc. Can. Further, in a peer-to-peer wireless network configuration, a UE can communicate with other UEs (and / or base stations with other base stations).

  Heterogeneous wireless communication systems can typically include various types of base stations, each of which can be associated with a different cell size. For example, a macrocell base station generally leverages antenna (s) installed with masts, rooftops, other existing structures, or the like. In addition, macrocell base stations often have a power output on the order of tens of watts and can provide coverage for large areas. Femto cell base stations are another class of base stations that have recently emerged. Femtocell base stations are typically designed for home or small business environments, and include wireless technology (eg, 3GPP Universal Mobile Telecommunications System (UMTS) or Long Term Evolution (LTE). ) 1x Evolution-Data Optimization (1xEV-DO), ...) to provide radio coverage for UEs and existing broadband Internet connection (eg, digital subscription) for backhaul A user line (DSL), cable,...) And the UE. A femtocell base station may also be referred to as a home evolved node B (HeNB), home node B (HNB), femtocell, or the like. Examples of other types of base stations include pico cell base stations, micro cell base stations, and the like.

  In some scenarios, some femtocell base stations or other base stations in the network may be restricted for access in some manner. For example, different base stations in the network can belong to different closed subscriber groups (CSG). In various situations, access control problems can arise due to the lack of synchronization between the UE and the network. More specifically, the UE may use some form of list (eg, whitelist,...) To identify the base stations that it is allowed to access. The list maintained by the UE can be read-only and operator controlled. Furthermore, the network can have an equivalent list. Problems can arise when the UE is removed from the CSG. For example, if the UE is removed from the CSG and the list stored by the UE before the UE attempts to access the CSG cell from the CSG is not updated, the UE will grant authorization for this CSG. A reject message can be received indicating that it lacks (authorization). Furthermore, since the list stored by the UE is read-only, the UE cannot be authorized to change the entry in the list stored by the UE, and therefore removes the CSG from such stored list. I can't. If the CSG is still included in the list saved by the UE, the UE can try again to access the CSG cell from the CSG, indicating that the UE lacks authorization for this CSG You can receive a reject message again.

  Further, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or”. That is, unless specified or clear from context, the phrase “X employs A or B” means any of the natural inclusive substitutions. Is intended. That is, the phrase “X uses A or B” is the next example, “X uses A”, “X uses B”, or “X uses both A and B” Will be satisfied by any of Further, as used in the present application and claims, the articles “a” and “an”, unless otherwise specified, or unless otherwise specified in the context of the singular, “one or It should be generally interpreted to mean “plurality”.

  Various techniques described herein may be used in various wireless communication systems, such as code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access ( OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, and other such systems. The terms “system” and “network” are often used interchangeably. A CDMA system may implement a radio technology such as Universal Terrestrial Broadcast Access (UTRA), cdma2000. UTRA includes Wideband CDMA (W-CDMA) and other variants of CDMA. In addition, cdma2000 covers IS-2000, IS-95, and IS-856 standards. A TDMA system may implement a radio technology such as a global system for mobile communications (GSM). The OFDMA system includes evolved UTRA (E-UTRA), Ultra Mobile Broadband (UMB), IEEE 802.20 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDM (registration). Wireless technology such as trademark) can be implemented. UTRA and E-UTRA are part of the Universal Mobile Telecommunications System (UMTS). 3GPP Long Term Evolution (LTE) is a release of UMTS that uses E-UTRA, which utilizes OFDMA on the downlink and SC-FDMA on the uplink. UTRA, E-UTRA, LTE and GSM are described in documents from an organization named “3rd Generation Partnership Project” (3GPP). Further, CDMA2000 and Ultra Mobile Broadband (UMB) are described in documents from an organization named “3rd Generation Partnership Project 2” (3GPP2).

  Single carrier frequency division multiple access (SC-FDMA) uses single carrier modulation and frequency domain equalization. SC-FDMA has substantially the same overall complexity and similar performance as that of an OFDMA system. The SC-FDMA signal has a peak power to average power ratio (PAPR) because of its inherent single carrier structure. SC-FDMA can be used, for example, in uplink communications where lower PAPR greatly benefits the access terminal in terms of transmit power efficiency. Thus, SC-FDMA can be implemented as an uplink multiple access scheme in 3GPP Long Term Evolution (LTE) or Evolved UTRA.

  Moreover, various aspects or features described herein can be implemented as a method, apparatus, or article of manufacture using standard programming and / or engineering techniques. The term “article of manufacture” as used herein is intended to include a computer program accessible from any computer-readable device, carrier, or media. For example, computer readable media include, but are not limited to, magnetic storage devices (eg, hard disks, floppy disks, magnetic strips ...), optical disks (eg, compact disks (CD), digital Digital versatile disk (DVD)...), Smart cards, and flash memory devices (eg, cards, sticks, key drives, etc.).

The term “machine-readable medium” includes, but is not limited to, wireless channels and various types that can store, include, and / or carry instruction (s) and / or data. Other media can be included.

  With reference to FIG. 1, illustrated is a wireless communication system 100 in accordance with various embodiments presented herein. System 100 comprises a base station 102 that can include multiple antenna groups. For example, one antenna group can include antenna 104 and antenna 106, another group can include antenna 108 and antenna 110, and an additional group can include antenna 112 and antenna 114. Although two antennas are shown for each antenna group, more or fewer antennas can be utilized for each group. Base station 102 may include a transmitter chain and a receiver chain, each of which is associated with a plurality of components (eg, processors, modulators) associated with signal transmission and reception, as will be appreciated by those skilled in the art. , Multiplexer, demodulator, demultiplexer, antenna, etc.) can be provided instead.

  Although base station 102 can communicate with one or more user equipments (UEs) such as UE 116 and UE 122, base station 102 can communicate with virtually any number of UEs similar to UEs 116 and 122. It should be understood that they can communicate. The UEs 116 and 122 are for communicating over, for example, cellular phones, smart phones, laptops, handheld communication devices, handheld computing devices, satellite radio, global positioning systems, PDAs, and / or wireless communication systems 100. Of any other suitable device. As shown, UE 116 is in communication with antenna 112 and antenna 114, which transmits information to UE 116 on forward link 118 and from UE 116 on reverse link 120. Receive information. Further, UE 122 is in communication with antenna 104 and antenna 106, which transmits information to UE 122 on forward link 124 and receives information from UE 122 on reverse link 126. . In a frequency division duplex (FDD) system, for example, the forward link 118 can utilize a different frequency band than that used by the reverse link 120, and the forward link 124 is utilized by the reverse link 126. Different frequency bands can be used. Further, in a time division duplex (TDD) system, forward link 118 and reverse link 120 can use a common frequency band, and forward link 124 and reverse link 126 use a common frequency band. can do.

  Each group of antennas and / or the area in which they are designed to communicate may be referred to as a sector of base station 102. For example, antenna groups can be designed to communicate to UEs in a sector of the area covered by base station 102. In communication on forward links 118 and 124, the transmit antenna of base station 102 may utilize beamforming to improve the signal-to-noise ratio of forward links 118 and 124 for UEs 116 and 122. Also, the base station 102 utilizes beamforming to transmit to randomly scattered UEs 116 and 122 through the associated coverage, but the UEs in neighboring cells have a single antenna for all their UEs. Compared to a base station transmitting through, there is a possibility of receiving less interference.

  It is anticipated that base station 102 can be any type of base station (eg, macrocell base station, microcell base station, picocell base station, femtocell base station,...). Further, the base station 102 can operate in a closed access mode, for example. When utilizing the closed access mode, the base station 102 is a closed subscriber group (CSG) base that allows users in the selected group identified by the CSG identifier (ID) to access such base stations. Can operate as a station. However, it should be understood that the claimed subject matter is not so limited (eg, base station 102 can operate in a hybrid access mode, an open access mode,...).

  A CSG base station refers to a base station with a restricted association that is accessible by members of the CSG (eg, inaccessible by non-members of the CSG,...). A CSG base station may also be referred to as a closed base station. The CSG is a set of base stations that share a common access control list of UEs. Further, the CSG base station can inform a corresponding CSG ID (eg, CSG identity,...), Which specifies the CSG corresponding to the CSG base station.

  Base station 102 can broadcast information to UE 116 and UE 122. The broadcast information can include, for example, a CSG ID that identifies the CSG associated with the base station 102. A CSG ID is a binary-based identifier associated with a subscriber group. The CSG ID can be used to identify a subscriber group (eg, CSG,...) Associated with the CSG base station, and to support constrained association for the CSG base station. Can be used to. Although the CSG ID can uniquely identify the CSG associated with the CSG base station, the claimed subject matter is not so limited. Furthermore, the CSG ID associated with a base station is generally not based on an Internet Protocol (IP) address. It is also anticipated that one or more base stations can share a common CSG ID, but the claimed subject matter is not so limited.

  When a UE (eg, UE 116, UE 122,...) Roams across the network, the UE may use a list (eg, a white list) stored by the UE to identify base stations that the UE is allowed to access. ...) can be used. The list maintained by the UE can be read-only. Furthermore, the read-only list can be controlled by the operator. For example, when the network gets information about which CSG the UE is allowed to access, the network node (eg, CSG list server,...) Instructs the UE to update the read-only list. , A message to the UE can be sent. For example, application level updates can be utilized to update a read-only list stored by the UE. For example, application level updates can be managed by an operator using over-the-air (OTA) procedures or open mobile alliance device management (OMA DM) procedures. However, it is to be understood that the claimed subject matter is not limited to the foregoing.

  A read-only list stored by the UE and controlled by the operator may be referred to as an operator CSG list. A problematic scenario can occur when a UE is removed from the CSG when implementing a conventional approach. For example, if the UE is removed from the CSG, and if the UE's operator CSG list is not updated before the UE attempts to access a CSG cell (eg, CSG base station, ...) from the CSG, the UE , Can receive a reject message indicating that the UE lacks authorization for this CSG (eg, the reject message can indicate cause # 25-not authorized for this CSG, ...・). Since the operator CSG list is read-only, the UE may not be able to remove the entry corresponding to the CSG from the operator CSG list, and the UE may also be unable to access the CSG cell (eg, , UE lacks permission to access CSG cell, ...).

  The system 100 can mitigate the detrimental effects associated with the aforementioned problematic scenarios that are often expressed in connection with the prior art. Since UEs (eg, UE 116, UE 122,...) Of system 100 are not authorized, access to a CSG cell (eg, CSG base station,...) Can be avoided. More specifically, the UE can save the CSG entry removed from the CSG subscription in the network, but can continue to be included in the operator CSG list maintained by the UE. Thus, upon receiving a reject message with a CSG ID included in the operator CSG list indicating that the UE lacks authorization for the CSG, the UE accordingly responds with a set of forbidden CSG identifiers (ID). The CSG ID can be stored as the prohibited CSG ID of the UE in. A CSG cell associated with a CSG with a corresponding CSG ID stored as a forbidden CSG ID in a set of forbidden CSG IDs may be deemed inappropriate for access by the UE, and therefore While the corresponding CSG ID is included in the set of forbidden CSG IDs, the UE stops selecting to access such CSG cells.

  With reference to FIG. 2, illustrated is a system 200 that supports recovering from a lack of synchronization between a network and a UE in a wireless communication environment. System 200 includes a UE 202 that can transmit and / or receive information, signals, data, instructions, commands, bits, symbols, and the like. Further, although not shown, system 200 can include any number of different UE (s) that can be substantially similar to UE 202. UE 202 may communicate with base station 204 via the forward link and / or reverse link. Base station 204 can transmit and / or receive information, signals, data, instructions, commands, bits, symbols, and the like. Further, although not shown, it is anticipated that any number of base stations similar to base station 204 may be included in system 200. Further, it is anticipated that the base station 204 can be any type of base station (eg, femtocell base station, picocell base station, microcell base station, macrocell base station,...).

  According to an example, base station 204 can be a CSG base station and thus can operate in a closed access mode. For example, if the base station 204 is a CSG base station, the base station 204 can be associated with a CSG, and the CSG can be identified by a CSG ID. A CSG can be uniquely identified (eg, globally,...) By, for example, a CSG ID. According to another example, a CSG can be uniquely identified by a CSG ID in an operator network. Further, the base station 204 can notify the CSG ID. In accordance with another illustration, different base station (s) (not shown) included in system 200 can be CSG base station (s), hybrid base station (s), and / or open base. It can be a station (s). Thus, the system 200 can utilize a mixed base station arrangement where one base station is hybrid and another base station is CSG or open. In accordance with this description, a different base station (s) that is a CSG base station (s) can be associated with a respective CSG (s), and each of the respective CSG (s) is , Corresponding to each CSG ID (s).

  Further, system 200 can include one or more network node (s) 206. For example, a Universal Terrestrial Radio Access Network (UTRAN) architecture for CSG provisioning and access control can be utilized. According to this example, the network node (s) 206 includes a mobile switching center (MSC) / visitor location registration (VLR), a serving general packet radio service (GPRS) support node (SGSN), a gateway GPRS support node (GGSN). ), Home subscriber server (HSS) / home location registration (HLR), policy and charging rule function (PCRF), and so on. In another example, an evolved universal terrestrial radio access network (E-UTRAN) architecture for CSG provisioning and access control can be utilized. In accordance with this example, network node (s) 206 includes packet data network gateway (PGW), serving gateway (SGW), mobility management entity (MME), HSS / HLR, PCRF, and the like. be able to. Further, although not shown, the system 200 can include CSG provisioning elements such as, for example, a CSG list server, a CSG administration server, and the like. However, it is to be understood that the claimed subject matter is not limited to the example architecture.

  The UE 202 can include an operator CSG list 208. The operator CSG list 208 can be stored in the UE 202 and can be under limited operator control. Operator CSG list 208 may include a CSG ID and / or an associated public land mobile network (PLMN) identity of the CSG to which the subscriber belongs. The operator CSG list 208 is stored, for example, in a universal subscriber identity module (USIM) (not shown) (or a subscriber identity module (SIM) (not shown)) of the UE 202. Can be done. However, it is further anticipated that operator CSG list 208 may be maintained in any other type of memory (not shown) of UE 202. The memory can be either volatile memory or non-volatile memory, or can include both volatile and non-volatile memory. By way of example, and not limitation, non-volatile memory may include read only memory (ROM), programmable ROM (PROM), electrically programmable ROM (EPROM), electrically erasable PROM (EEPROM), or flash memory. I can do it. Volatile memory can include random access memory (RAM), which acts as external cache memory. By way of example and not limitation, the RAM may be synchronous RAM (SRAM), dynamic RAM (DRAM), synchronous DRAM (SDRAM), double data rate SDRAM (DDRSDRAM), extended SDRAM (ESDRAM), sync link DRAM (SLDRAM). ), And direct Rambus RAM (DRRAM). The memory of the subject system and method is intended to comprise these and any other suitable type of memory without limitation.

  The operator CSG list 208 can only be read by the UE 202. Further, the operator CSG list 208 can be provisioned using an OMA DM procedure or an OTA procedure. For example, an OTA procedure can be used to provision operator CSG list 208 when UE 202 has a release 9 USIM, but provision UE CSG list 208 when UE 202 has a pre-release 9 USIM. An OMA DM procedure can be used for this purpose. As another explanation, an OTA procedure can be used to provision operator CSG list 208 if UE 202 has a release 8 USIM, but operator CSG list 208 can be used if UE 202 has a pre-release 8 USIM. Can be used to provision. However, it should be understood that the claimed subject matter is not limited to the foregoing examples.

  Further, the UE 202 automatically accesses the CSG cell associated with the CSG (eg, corresponding to the base station 204,...) With the corresponding CSG ID included in the operator CSG list 208 of the UE 202. A selection component 210 that can be selected can be included. The selection component 210 can implement manual or automatic selection (or reselection). When utilizing manual CSG selection, the selection component 210 can use an available CSG cell (eg, base station) regardless of whether the CSG ID corresponding to the available CSG cell is present or absent in the operator CSG list 208. 204, corresponding to different base station (s) (not shown), corresponding to 204, can be searched. Further, the selection component 210 can detect a set of available CSG cells that can be selected (eg, suitable or acceptable for access,...) And a set of available CSG cells. An input identifying a manually selected CSG cell that has been selected to be accessed by UE 202 may be received.

  According to the description, when searching for available CSG cell (s), the selection component 210 can notify the notification CSG ID (eg, one or more) sent by the base station 204 that identifies the CSG corresponding to the base station 204. The same applies to notification CSG ID (s) of a plurality of different base stations. Further, the selection component 210 can obtain input related to a manually selected CSG cell from a set of available CSG cells. For example, input can be provided manually by a user of UE 202. According to this example, the selection component 210 can display a list of CSG cells available in a set of selections (eg, via a graphical user interface (GUI)...) And displayed An input identifying a manually selected CSG cell according to the list may be received. Also, the claimed subject matter is not so limited.

  The selection component 210 can cause the UE 202 to request access to the base station 204 based on either manual or automatic selection (or reselection). For example, UE 202 may access a CSG cell (eg, base station 204,...) Associated with a CSG with a corresponding CSG ID in operator CSG list 208 as achieved by selection component 210. When selected, attach request message, detach request message, tracking area update request message (tracking area update request message), location area update request message (location area updating request message), routing area update request message (routing area update request message) , Or the like. Further, the UE 202 may attach a attach request message, a detach request message, a tracking area update request message, a location area update request message, a routing area update request message, or the like. Depending on, an acceptance message or a rejection message can be received.

  When UE 202 requests access to base station 204, one or more of network node (s) 206 determines whether UE 202 is authorized to access such base station 204. Can be evaluated. At least one of the one or more of the network node (s) 206 that evaluates whether the UE 202 is authorized to access the base station 204 may include an access control component 212. As an example, CSG subscription data can be stored permanently in the HSS / HLR for access control during an attach procedure, service request procedure, or tracking / location / routing area update procedure To MME, MSC / VLR, and / or SGSN. When UE 202 accesses a CSG cell (eg, base station 204,...), Access control of the first of the network node (s) (eg, MME, SGSN, MSC,...) Component 212, the CSG ID of the CSG cell corresponds to the CSG ID in the subscription data retrieved from the second of the network node (s) 206 (eg, HSS / HLR,...); You can check that the expiration time remains valid (if it exists). Further, if the CSG ID does not exist in the subscription data or if the timer expires, the first of the network node (s) 206 (such as MME, SGSN, MSC,...) 206 Access control component 212 may send a reject message to UE 202 with an error code (eg, error code # 25,...) Indicating that UE 202 is not authorized for this CSG. Thus, assuming that the base station 204 is associated with a CSG cell, the access control component 212 of the network node (s) 206 is notified by the CSG cell (eg, base station 204,...). Access control can be performed based on the ID and CSG subscription data of UE 202 stored in the network.

  The UE 202 may further include a forbidden CSG management component 214 and a set of forbidden CSG IDs 216. A reject message (e.g., indicating that UE 202 lacks authorization for a CSG associated with a CSG cell (e.g., base station 204, ...) where UE 202 (e.g., forbidden CSG management component 214, ...) When the error code # 25,... is received, the forbidden CSG management component 214 determines that the UE 202 in the set of forbidden CSG IDs 216 in response to when the CSG ID is included in the operator CSG list 208. A CSG ID corresponding to the prohibited CSG ID can be stored. The forbidden CSG management component 214 can add and remove forbidden CSG IDs from the set of forbidden CSG IDs 216, as described in further detail herein. As a further example, the forbidden CSG management component 214 can store, in a set of forbidden CSG IDs 216, each PLMN identity associated with a CSG cell with the forbidden CSG ID.

  A set of forbidden CSG IDs 216 can include forbidden CSG IDs 1,..., And forbidden CSG IDs X, where X is substantially any integer value. Can be. It should be understood that these CSG IDs can be in the form of bit strings or any other format. Further, although not shown, a set of forbidden CSG IDs 216 can be an empty set at a given time (eg, any forbidden CSG ID is missing, ...) It is expected that. It is also understood that a set of forbidden CSG IDs 216 can include one forbidden CSG ID at a particular time (eg, forbidden CSG ID 1,...). According to an example, a set of forbidden CSG IDs 216 can be stored in the forbidden CSG list of UE 202. Following this example, the forbidden CSG list can be a read-write list maintained by the UE 202. However, it should be understood that the claimed subject matter is not limited to the examples described above.

  The forbidden CSG management component 214 can temporarily store the CSG ID (s) as the forbidden CSG ID (s) in a set of forbidden CSG IDs 216, and CSG ID ( Is deleted from the CSG subscription data of UE 202 stored in the network, but has not been deleted from operator CSG list 208 yet. Accordingly, a set of forbidden CSG IDs 216 is leveraged by UE 202 to avoid accessing unauthorized CSG cells (eg, base stations 204,...) That are not authorized but continue to be included in operator CSG list 208. be able to.

  The set of forbidden CSG IDs 216 can include the CSG ID of the CSG that the UE 202 receives a reject message indicating that the UE 202 lacks authorization for the CSG, however, they are included in the operator CSG list 208 . Since the operator CSG list 208 is read-only with respect to the UE 202, for example, the prohibited CSG ID is 1 until the operator CSG list 208 is updated (eg, until the UE 202 performs the next application level update ...) 1 Can be stored with a CSG ID 216 that is forbidden to set. For example, a set of forbidden CSG IDs 216 can be temporarily retained (eg, in the USIM of UE 202, in the memory of UE 202, etc.), and further, the UE 202 is in the application level of the operator CSG list 208. A set of forbidden CSG IDs 216 can be deleted by the forbidden CSG management component 214 when performing an update. It should also be understood that the claimed subject matter is not limited to the above example, because the prohibited CSG management component 214 may receive a USIM from the UE 202 when the UE 202 is switched off. Deleting a set of forbidden CSG IDs 216 when removed, periodically (eg, 12 hours, 24 hours, 48 hours, virtually any time period, etc.), etc. This is because it is expected to be possible.

  If the UE 202 is removed from the CSG or the membership of the UE 202 in the CSG expires before the operator CSG list 208 is updated (eg, the CSG subscription of the UE 202 stored in the network) When maintained in the data ...), the forbidden CSG management component 214 receives the deny message sent by the network (eg, brought about by the access control component 212, ...) Can be achieved. If the CSG ID is included in the operator CSG list 208, the forbidden CSG management component 214 of the UE 202 adds a CSG ID to a set of forbidden CSG IDs 216 (eg, forbidden CSG list,...). can do. Further, the forbidden CSG management component 214 deletes a set of forbidden CSG IDs 216 after the UE 202 performs the next successful update of the operator CSG list 208 using, for example, an OTA or OMA DM procedure. Can do. Additionally or alternatively, the forbidden CSG management component 214 has a set of forbidden when the UE 202 is switched off, when removing the USIM for the UE 202, periodically, or similar The CSG ID 216 can be deleted. Further, CSG cells belonging to a CSG ID stored in a set of forbidden CSG IDs 216 may be deemed inappropriate for access by UE 202. Thus, a set of forbidden CSG IDs 216 can support scenarios where the UE 202 operator CSG list 208 is not synchronized with the UE 202 CSG subscription data stored in the network.

  With reference to FIG. 3, illustrated is a system 300 that identifies CSG cells available for access in a wireless communication environment. System 300 includes UE 202, base station 204, and network node (s) 206. The UE 202 can include an operator CSG list 208 that can be read-only and controlled by an operator, and a set of forbidden CSG IDs 216. Further, the UE 202 can include a selection component 210 and a prohibited CSG management component 214.

  The UE 202 can further include an authorized CSG list 302 that can be updated by the UE 202. For example, when UE 202 performs manual cell selection or some other similar procedure, UE 202 is granted access to a cell associated with a CSG ID that does not currently exist in operator CSG list 208. The allowed CSG list 302 can be updated. The UE 202 can read and write permissions for the allowed CSG list 302. Further, the allowed CSG list 302 can be stored on the USIM of the UE 202, can be maintained in the memory of the UE 202, and the like.

  According to one example, if an entry (eg, CSG ID,...) Is added to the UE 202 CSG subscription data stored in the network but not yet added to the UE 202 operator CSG list 208, the entry is If the UE 202 accesses the CSG before the CSG list 208 is updated, it can be added to the allowed CSG list 302. Further, if the CSG ID stored in the authorized CSG list 302 occurs in the operator CSG list 208 after the operator CSG list 208 is updated (eg, via application level update, ...), the UE 202 Can remove the corresponding CSG ID in the allowed CSG list 302. However, it is to be understood that the claimed subject matter is not limited to the foregoing.

  As another example, if an entry (eg, CSG ID,...) Is removed from CSG subscription data for UE 202 stored in the network, forbidden CSG management component 214 may cause UE 202 to lack authorization for CSG. The following procedure can be achieved by receiving a rejection message indicating that: If the CSG ID is included in the allowed CSG list 302, the entry can be deleted from the allowed CSG list 302 by the prohibited CSG management component 214. Furthermore, the UE 202 can avoid accessing the CSG cell associated with the CSG ID.

Further, the UE 202 can include a filter component 304 that can identify CSG cells that are suitable or inappropriate for access by the UE 202. For example, the filter component 304 has a set of prohibited CSG cells belonging to a CSG ID that are not included in the operator CSG list 208 or allowed CSG list 302 or that are inappropriate for access by the UE 202. Included in CSG ID 216 (eg, included in forbidden CSG list,...). Accordingly, the selection component 210 can prevent automatic selection (or reselection) of CSG cells deemed inappropriate for access by the filter component 304. For manual selection of CSG cells, it should be understood that the selection component 210 can select CSG cells that are inappropriately accessed by the UE 202 as determined by the filter component 304.

  For example, the CSG cell associated with a CSG with a corresponding CSG ID stored as a forbidden CSG ID in a set of forbidden CSG IDs 216 as filter component 304 is unsuitable for access by UE 202 (E.g., base station 204, ...) can be considered. Further, the filter component 304 can consider a CSG cell with a CSG ID that is omitted from the operator CSG list 208 and omitted from the allowed CSG list 302 as inappropriate for access by the UE 202. However, it is to be understood that the claimed subject matter is not so limited.

  According to another example, the filter component 304 removes the CSG ID from the set of forbidden CSG IDs 216 from the set of CSG IDs included in the operator CSG list 208 to yield the remaining subset of CSG IDs. Can do. According to this example, a CSG cell associated with a CSG with a corresponding CSG ID included in the remaining subset of CSG IDs may be deemed appropriate for access by UE 202. The filter component 304 may or may not include the allowed CSG list 302,... Regardless of whether or not the allowed CSG list 302 is utilized by the UE 202, The CSG ID included in the set of forbidden CSG IDs 216 can be removed from the set of CSG IDs included in the operator CSG list 208. However, it is to be understood that the claimed subject matter is not so limited.

  With reference to FIG. 4, illustrated is a system 400 that performs CSG selection in a wireless communication environment. System 400 includes UE 202, which can further include an operator CSG list 208, a selection component 210, a prohibited CSG management component 214, a set of prohibited CSG IDs 216, and a filter component 304. Further, the UE 202 can include a display component 402 that can render available CSG IDs and associated PLMN identities. For example, the display component 402 can render a PLMN identity associated with a CSG ID that is available via the GUI.

  Operator CSG list 208 may include a list of authorized CSG IDs and associated PLMN identities. Further, although not shown, it is expected that UE 202 may include an authorized CSG list (eg, authorized CSG list 302,... In FIG. 3), which is also authorized. And a list of associated CSG IDs and associated PLMN identities. However, the claimed subject matter is not limited to a UE 202 that includes an authorized CSG list.

  The selection component 210 can support automatic CSG selection or manual CSG selection. For example, for automatic CSG selection, the PLMN can be selected by the selection component 210. In addition, the selection component 210 can select the CSG ID for automatic CSG selection if the cell is not a CSG cell or is included in the operator CSG list 208 (or included in the allowed CSG list of the UE 202 if used). If the cell is a CSG cell with, the cell can be camped on to UE 202 in the selected PLMN.

  As another example, for manual CSG selection, display component 402 can show a list of available CSG IDs and associated PLMN identities. Further, the selection component 210 can obtain input specifying a selection from a PLMN identity associated with a list of available CSG IDs. Further, the selection component 210 can accomplish camping on the cell with the selected CSG ID and attempting to register with the PLMN corresponding to the associated PLMN identity based on the input. it can.

If a reject message is received by the UE 202 indicating that the UE 202 lacks authorization for the CSG, the following can be implemented. According to an example, if the reject message indicates that the UE 202 lacks authorization for a CSG with a corresponding CSG ID present in the operator CSG list 208, the filter component 304 (eg, non-access stratum (NAS) Blocking the PLMN identity associated with the CSG ID from being included in the list of allowed CSG IDs and the associated PLMN identity provided to the access stratum (AS) Can do. As another example, when utilizing manual CSG selection (eg, via selection component 210,...), Filter component 304 associates a CSG ID as being in operator CSG list 208 stored by UE 202. The display component 402 can be prevented from displaying the PLMN identity provided. According to this example, the CSG ID stored in a set of forbidden CSG IDs 216 (eg, as controlled by the forbidden CSG management component 214,...) Is included in the operator CSG list 208. It can be prevented from being displayed (eg, by display component 402,...) (Eg, by filter component 304,...). Thus, when a CSG ID is stored as a forbidden CSG ID in a set of forbidden CSG IDs 216, it is assumed that UE 202 is associated with a member CSG (eg, by display component 402,...). Displaying the CSG ID can be prevented by the filter component 304. According to yet another example, if the authorized CSG list is used by UE 202, the NAS can remove the CSG ID from the authorized CSG list if present, but the claimed subject matter It should be understood that the matter is not so limited.

  For manual CSG selection, the filter component 304 includes a set of operators included in the operator CSG list 208 to provide a subset of CSG IDs for displays that are to exist in the operator CSG list 208 via the display component 402. From the CSG ID, the CSG ID (s) in the set of forbidden CSG IDs 216 can be removed. Removing such CSG ID (s) in the set of forbidden CSG IDs 216 can be accomplished to mitigate user confusion, thus enhancing the user experience. In contrast, after UE 202 is rejected in the CSG cell corresponding to the CSG ID in operator CSG list 208 (eg, after receiving a reject message indicating that UE 202 lacks authorization for CSG ... ), If the display component 402 indicates that the UE 202 is a member of the CSG, the user may be confused when a manual selection is performed, and the display component 402 may have a CSG corresponding to the CSG ID. Continue to show that you are a member of.

  Further, the forbidden CSG management component 214 can remove the CSG ID (s) from the set of forbidden CSG IDs 216. According to an example, the forbidden CSG management component 214 can erase a set of forbidden CSG IDs 216. According to this example, erasing a set of forbidden CSG IDs 216 is when switching off UE 202, removing USIM from UE 202, periodically, when operator CSG list 208 is updated, etc. Can be achieved by the forbidden CSG management component 214.

  As another example, the forbidden CSG management component 214 can remove the CSG ID from the set of forbidden CSG IDs 216. The forbidden CSG component 214 can remove the CSG ID from the set of forbidden CSG IDs 216 when a CSG cell with the forbidden CSG ID is manually selected (eg, using the selection component 210). ...) UE 202 accesses the CSG cell and UE 202 receives the accept message accordingly. Accordingly, UE 202 is accepted in the CSG cell.

  For example, UE 202 may send an attach request message to a CSG cell corresponding to a CSG ID stored as a forbidden CSG ID in a set of forbidden CSG IDs 216 based on manual CSG selection achieved by selection component 210. Can be sent. The UE 202 can receive an attach accept message from the CSG cell in response to the attach request message. Accordingly, the prohibited CSG management component 214 can remove the CSG ID from the set of prohibited CSG IDs in response to receiving the attach accept message. According to another description, UE 202 requests a CSG cell corresponding to a CSG ID stored as a forbidden CSG ID in a set of forbidden CSG IDs 216 based on manual CSG selection achieved by selection component 210. A message can be sent, and the request message can be a tracking area update request message, a location area update request message, a routing area update request message, or the like. Further, the UE 202 can receive an acceptance message from the CSG cell in response to the request message, and the acceptance message can be a tracking area update acceptance message, a location area update acceptance message, a routing area update acceptance message, or the like. Further, the forbidden CSG management component 214 can remove the CSG ID from the set of forbidden CSG IDs 216 in response to receiving the acceptance message. As yet another example, the CSG ID can be removed from the set of forbidden CSG IDs 216 when the CSG ID is removed from the operator CSG list 208. However, it should be understood that the claimed subject matter is not limited to the foregoing examples.

  With reference to FIG. 5, illustrated is a system 500 that provisions an operator CSG list (eg, operator CSG list 208,...) Of a UE (eg, UE 202,...) In a wireless communication environment. System 500 includes UE 202 and CSG list server 502. The UE 202 may further include an operator CSG list 208, a selection component 210, a forbidden CSG management component 214, a set of forbidden CSG IDs 216, and / or a list management component 504.

  The CSG list server 502 can be utilized to provision the operator CSG list 208 of the UE 202 using OMA DM or OTA procedures. Furthermore, the CSG list server 502 can update the operator CSG list 208 of the UE 202. Accordingly, if the CSG ID is removed or added from the CSG subscription data of UE 202 stored in the network, CSG list server 502 can remove or add the CSG ID from UE 202 operator CSG list 208.

  However, it should be understood that the UE 202 may be removed from the CSG before the CSG list server 502 updates the operator CSG list 208 to delete the CSG ID corresponding to the CSG. According to another description, the UE 202 membership to the CSG may expire before the CSG list server 502 updates the operator CSG list to delete the CSG ID corresponding to the CSG. The foregoing has received a reject message indicating that UE 202 lacks authorization for CSG in response to selecting to access a CSG cell associated with a CSG with a corresponding CSG ID included in operator CSG list 208. It may result in the UE 202 receiving. Accordingly, the forbidden CSG management component 214 can save the CSG ID as the forbidden CSG ID in the set of forbidden CSG ID 216 in response to receiving the reject message.

  As an example, the list management component 504 may update the operator CSG list 208 when at least one forbidden CSG ID is saved by the UE 202 (eg, in a set of forbidden CSG IDs 216...). Can start. For example, the list management component 504 can cause the CSG list server 502 to update the operator CSG list 208 under such conditions. According to an example, starting to update the operator CSG list 208 is when at least one forbidden CSG ID is saved by the UE 202 (eg, in a set of forbidden CSG IDs 216...). At the next access, this can be accomplished by the list management component 504. As another example, the list management component 504 can determine a predetermined amount of time that at least one forbidden CSG ID is stored by the UE 202 (eg, in a set of forbidden CSG IDs 216). After that, the operator CSG list 208 can begin to be updated.

  FIG. 6 illustrates an example communication system 600 that enables deployment of access point base stations (eg, femtocell base stations) in a network environment. As shown in FIG. 6, system 600 includes multiple femtocell base stations, which are an access point base station, a home evolved Node B unit (HeNB), a home Node B unit (HNB), a femto. It can also be called a cell, or the like. A femtocell base station (HeNB 610) may be installed, for example, in a corresponding small network environment, eg, in one or more user homes 630, respectively, in addition to aliens, associated UEs ( The service (s) 620 can be configured to serve. Each HeNB 610 can be further coupled to the Internet 640, a mobile operator core network 650 via a DSL router (not shown), or alternatively, a cable modem (not shown).

  Although the embodiments described herein use 3GPP terminology, the embodiments are based on 3GPP (Rel99, Rel5, Rel6, Rel7) technology, 3GPP2 (1xRTT, 1xEV-DO Rel0, RevA, RevB) technology and others. It should be understood that it can be applied to any known related art. In such embodiments described herein, the owner of the HeNB 610 can subscribe to a mobile service, such as a 3G mobile service provided through the mobile operator core network 650, and the UE 620 It is possible to operate in both the macro cell environment and the home small network environment. Thus, the HeNB 610 can be backward compatible with any existing UE 620. It is anticipated that the HeNB 610 may include CSG HeNB (s), hybrid HeNB (s), and / or open HeNB (s).

  With reference to FIG. 7, illustrated is an example system 700 that provides closed subscriber groups (CSGs) in a wireless communication environment. System 700 illustrates an exemplary architectural model that can be used with HeNB 702 (eg, HeNB 610 in FIG. 6, base station 204 in FIG. 2,...). However, it is anticipated that different architectural models are intended to fall within the scope of the claims. For example, although not shown, different architectures that support using a CSG with HNB, a macrocell base station, or any other type of base station are within the scope of the claimed subject matter. It is expected to be intended.

  According to the figure, the HeNB 702 can be deployed on a user's premise, however, the claimed subject matter is not so limited. HeNB 702 can provide E-UTRAN eNB functions in addition to functions that support HeNB authentication, HeNB registration, and HeNB configuration through operations and maintenance (OAM).

  HeNB 702 directly with various nodes (eg, network node 206 (s) of FIG. 2) of the core network of system 700 (eg, evolved packet core (EPC),...). Or it can communicate indirectly. For example, the nodes of the core network may include PGW 704, SGW 706, MME 708, and HSS 710. Although not shown, it is anticipated that system 700 may include one or more PGW 704, SGW 706, MME 708, and / or HSS 710.

  The PGW 704 may interface with external packet data network (PDN) (s), such as the Internet 712 and / or IP Multimedia Subsystem (IMS) 714, for example. Further, although not shown, the PGW 704 may additionally or alternatively interface with the Internet or any different PDN (s). For example, the PGW 704 can handle address allocation, policy enforcement, packet classification and routing, and the like.

  The SGW 706 is associated with the user plane and is a mobility anchor point. SGW 706 points to a user's serving base station (eg, using UE 716,...) (Eg, HeNB 702, heterogeneous HeNB, different eNB,...). Thus, when handing off to different base stations, the SGW 706 can point back to the different base stations. Further, the SGW 706 may allow data to be routed to an appropriate base station (eg, HeNB 702,...) Serving the UE 716 at any time.

  The MME 708 is associated with the control plane. The MME 708 may support control plane signaling for mobility, quality of service (QoS) initialization, user authentication, and the like. In addition, the HSS 710 can store various subscription information such as phone numbers, profiles, and the like.

  System 700 includes various interfaces between nodes. For example, the S6a interface can be connected to MME 708 and HSS 710, and the S5 / S8 interface can be connected to SGW 706 and PGW 704. Further, the S1-U interface can be connected to the HeNB 702 and the SGW 706, the S11 interface can be coupled to the SGW 706 and the MME 708, and the S1-MME interface can be connected to the HeNB 702 and the MME 708. Furthermore, the PGW 704 can be connected to the PDN (s) (eg, Internet 712, IMS 714,...) Via respective SGi interfaces, and the HeNB 702 and UE 716 can be connected via the E-UTRA-Uu interface. Can be combined. Further, the MME 708 can be associated with an S10 interface to another MME (not shown).

  The HSS 710 may also connect directly or indirectly to CSG provisioning network elements, ie, CSG administration server 718 and CSG list server 720 (eg, CSG list server 502,... In FIG. 5). The CSG administration server 718 can support a CSG administration function, which is used to manage a list of subscribers for the CSG (eg, access control list for the CSG, ...). Can. For example, the owner of the HeNB 702 may use a CSG administration server 718 via an interface (eg, GUI, website,...) To add or remove users from being included in a CSG associated with the HeNB 702. Can be interfaced with. Based on such changes, the CSG administration server 718 can update the HSS 710 to adjust subscriber information about the user in response to the modification.

  Further, the CSG list server 720 may provide a whitelist (WL) (eg, operator CSG list 208 of FIG. 2, FIG. 3) for the UE 716 (and / or any different UE (s) (not shown)). UE CSG provisioning function used to manage the authorized CSG list 302,. The CSG list 720 can notify the UE 716 that it is a member of a specific group (eg, a specific CSG,...). Further, when a subscription is updated by the CSG administration server 718, the HSS 710 can store subscription information corresponding to the update. Further, updating the subscription information in HSS 710 can trigger a message to be transferred to CSG list server 720, which causes OMA-DM process or OTA process to utilize CSG list server 720 and causes UE 716 to The modified subscription information is transmitted in the downlink. Thus, the CSG list server 720 is maintained by the HSS 710 and the UE 716 (eg, maintained on the USIM or subscriber identity module (SIM) associated with the UE 716, stored in the memory of the UE 716, ...). Coordination of subscription information can be enabled.

  Various logical network protocol functions between the UE 716 and the core network element can be achieved in the system 700 to support CSG. For example, the logical network protocol functions can include UE CSG provisioning functions, access control functions, mobility management functions, and CSG administration functions.

  The UE CSG provisioning function can manage a whitelist for UE 716. The white list is a list of CSG IDs, and the UE 716 can access a CSG cell having a CSG ID included in the white list. The white list can be stored in the network to perform access control, and can be stored by the UE 716 to enable selecting cells to be accessed. The whitelist in the network can be permanently stored in the HSS 710 and can be retrieved by the MME 708 for access control during attach, detach, service request, and tracking area update procedures. The white list at the UE 716 can be stored on the USIM for the UE 716 or the UE 716 memory.

  The access control function can ensure that the UE has a valid subscription in the CSG performing the access. MME 708 (eg, access control component 212 of FIG. 2) accesses the network through the CSG cell to perform access control for UE 716 during attach, detach, service request, and tracking area update procedures. Can do. In addition, the MME 708 may include a rejection factor value in a non-access stratum (NAS) signaling response when recognizing that the UE 716 is not allowed in the CSG for attach, service request, and / or tracking area update procedures.

  Further, the mobility management function can be used to keep track of the current location of the UE 716. The location of the idle UE 716 can be known by the network on the Tracking Area granularity. Thus, when in the idle state, UE 716 can be paged in all cells in the tracking area list received in the last tracking area update.

  In addition, the CSG administration function can manage a list of subscribers for the CSG. The CSG administration function can be hosted by an operator or a third party. For example, the single list can control the HeNB for CSG. Further, the HeNB that notifies the same CSG ID may have a single list of subscribers.

  As described above, the HSS 710 can permanently retain CSG subscription information. Further, the CSG subscription information can be retrieved by the MME 708 during the attach procedure or tracking area update procedure as part of the UE 716 subscription profile. The MME 708 can use the retrieved CSG subscription information to perform access control. For example, the MME 708 can perform access control because the access control is a NAS level procedure, and the MME 708 is a NAS endpoint in the core network. Further, the MME 708 can obtain and store a copy of the whitelist for the UE 716 (eg, the whitelist can be maintained as part of the user's subscription information,...). Furthermore, the MME 708 can know the CSG ID of the CSG cell that the UE 716 is performing access to achieve access control.

  Although described herein as being implemented in a NAS, it is expected that access control for CSG can be implemented in an access stratum (AS). Access control in AS may be implemented in a radio network controller (RNC) function in HeNB 702 (or in a related function in a HeNB gateway (not shown)). However, it is to be understood that the claimed subject matter is not so limited.

  8-10, methodologies relating to managing access control to a CSG in a wireless communication environment are illustrated. To simplify the description, the method is shown and described as a series of operations, but it should be appreciated and understood that the method is not limited by the order of operations, Operations may occur in a different order and / or simultaneously with other operations from those shown and described herein, according to one or more embodiments. For example, those skilled in the art will understand and appreciate that a method could alternatively be represented as a series of interrelated states or events, such as in a state diagram. Moreover, not all illustrated acts may be required to implement a methodology in accordance with one or more embodiments.

  Returning to FIG. 8, illustrated is a methodology 800 that facilitates recovering from a lack of synchronization in a wireless communication environment. At 802, selecting to access a closed subscriber group (CSG) cell associated with a CSG with a corresponding CSG identifier (ID) included in an operator CSG list of a user equipment (UE) is achieved. Can do. Furthermore, the operator CSG list is read-only and can be controlled by the operator. For example, an attach request message, a detach request message, a tracking area update request message, a location area update request message, a routing area update request message, or the like is associated with a CSG with a corresponding CSG ID included in the operator CSG list. Selected to access the designated CSG cell can be transmitted. At 804, a reject message can be received indicating that the UE lacks authorization for the CSG. At 806, when the CSG ID is included in the operator CSG list, the CSG ID can be saved as a prohibited CSG ID of the UE in a set of prohibited CSG IDs in response to receiving a reject message. . Furthermore, the forbidden CSG ID can be stored in the forbidden CSG list of the UE. Further, the public land mobile network (PLMN) identity associated with the CSG cell can be stored as a forbidden CSG ID.

  According to an example, the UE can be removed from the CSG before the operator CSG list is updated to delete the CSG ID. As another example, UE membership for CSG may expire before the operator CSG list is updated to delete the CSG ID.

  A CSG cell can be perceived as appropriate or inappropriate for access by a UE as a function of at least an operator CSG list and a set of forbidden CSG IDs. For example, a given CSG cell associated with a given CSG with a corresponding CSG ID stored as a given forbidden CSG ID in a set of forbidden CSG IDs may not be accessible by the UE. Can be considered appropriate. According to another illustration, a set of forbidden CSG IDs can be removed from a set of CSG IDs included in an operator CSG list to yield a remaining subset of CSG IDs, where A CSG cell associated with a CSG with a corresponding CSG ID included in the CSG ID may be deemed appropriate for access by the UE. Furthermore, a CSG cell with a forbidden CSG ID may be deemed inappropriate for access by the UE. According to another example, a CSG cell with a CSG ID omitted from the operator CSG list and omitted from the UE's allowed CSG list may be deemed inappropriate for access by the UE, The permission of the permitted CSG list can be read and written.

  According to another example, an operator CSG list update can be initiated when at least one forbidden CSG ID is saved (eg, in a set of forbidden CSG IDs ...). For example, updating the operator CSG list may be initiated on the next access when at least one forbidden CSG ID is saved. According to another example, updating the operator CSG list may be initiated after a predetermined length of time while at least one forbidden CSG ID is stored. However, it should be understood that the claimed subject matter is not limited to the foregoing examples.

  As another example, a set of forbidden CSG IDs can be erased. According to this example, a set of forbidden CSG IDs can be used when the UE is switched off, when the Universal Subscriber Identity Module (USIM) is removed from the UE, periodically when the operator CSG list is updated, and It can be erased at a similar time. For example, the operator CSG list can be updated by the network (eg, CSG list server,...) Via an OMA DM procedure or an OTA procedure.

  According to another example, a CSG ID (or any similar different CSG ID) can be removed from a set of forbidden CSG IDs. The CSG ID can be removed from the set of forbidden CSG IDs when implementing manual CSG selection. For example, an attach request message can be transmitted to a CSG cell corresponding to a CSG ID stored as a prohibited CSG ID based on the manual CSG selection. Further, the attach acceptance message can be received from the CSG cell in response to the attach request message. Further, the CSG ID can be removed from the set of forbidden CSG IDs in response to receiving the attach accept message. As another example, a request message can be sent to a CSG cell corresponding to a CSG ID stored as a CSG ID prohibited based on manual CSG selection, where the request message is a tracking area update. It can be a request message, a location area update request message, and / or a routing area update request message. In accordance with this example, an acceptance message can be received from the CSG cell in response to the request message, where the acceptance message is a tracking area update acceptance message, a location area update acceptance message, and / or a routing area update acceptance. Can be a message. Further, the CSG ID can be removed from the set of forbidden CSG IDs in response to receiving the acceptance message. As yet another example, the CSG ID can be removed from a set of forbidden CSG IDs when the CSG ID is removed from the operator CSG list. However, it should be understood that the claimed subject matter is not limited to the foregoing examples.

Further, for example, when the CSG ID is included in the operator CSG list, the CSG ID is added to the list of allowed CSG identities provided to the access stratum (AS) for cell selection in response to receiving the reject message. Inclusion can be prevented . According to another description, displaying a CSG ID as being in the operator CSG list may be blocked for manual CSG selection mode when the CSG ID is saved as a prohibited CSG ID. As yet another example, displaying a CSG ID as being associated with a CSG that the UE is a member can be prevented when the CSG ID is saved as a prohibited CSG ID.

With reference to FIG. 9, illustrated is a methodology 900 that facilitates identifying appropriate cells for access in a wireless communication environment. At 902, a message can be received indicating that the user equipment (UE) is not authorized for the closed subscriber group (CSG). For example, the message can be received in response to accessing a CSG cell associated with the CSG. At 904, it can be recognized whether a CSG identifier (ID) corresponding to the CSG is present in the operator CSG list. Furthermore, the operator CSG list is read-only and can be controlled by the operator. At 906, when the CSG ID is present in the operator CSG list, including the CSG ID in the list of allowed CSG identities provided to the access stratum (AS) for cell selection can be prevented . In addition, a list of allowed CSG IDs can be provided to the AS by a non-access stratum (NAS). As another example, CSG ID is allowed for a period of time, such as until the UE is switched off, Universal Subscriber Identity Mode (USIM) is removed from the UE, or until the operator CSG list is updated. It was can be prevented from being included in the list of CSG ID.

Returning to FIG. 10, illustrated is a methodology 1000 that facilitates displaying an entry in an operator CSG list for a manual CSG selection mode in a wireless communication environment. At 1002, a message can be received indicating that the user equipment (UE) is not authorized for a closed subscriber group (CSG). For example, the message can be received in response to accessing a CSG cell associated with the CSG. At 1004, it can be recognized whether a CSG corresponding CSG identifier (ID) exists in the operator CSG list. Furthermore, the operator CSG list is read-only and can be controlled by the operator. At 1006, the UE may be blocked from indicating that there is a CSG ID in the operator CSG list stored at the UE for manual CSG selection mode. According to a further example, the operator CSG list stored at the UE for a time period such as until the UE is switched off, until the Universal Subscriber Identity Mode (USIM) is removed from the UE, and until the operator CSG list is updated. The UE can be blocked from indicating that the CSGID is present (eg, block its display,...).

  In accordance with one or more aspects described herein, inferences can be made regarding achieving management of access control for a CSG in a wireless communication environment that supports multiple access modes. As used herein, the term “infer” or “inference” generally refers to a system, environment, and / or from a set of observations captured via events and / or data. Or it refers to the process of inferring or inferring the state of the user. Inference can be employed to identify a specific context or action, or can generate a probability distribution over states, for example. This inference can be probabilistic, i.e., the computation of a probability distribution for the state of interest based on data and event considerations. Inference may refer to techniques employed for composing high-level events from a set of events / data. Such inference is based on multiple events and data, whether or not they are interrelated in close temporal proximity, and whether the event and the data originate from a single event and data source. What happens from the source results in a new event or new activity composition from a set of observed events and / or stored event data.

  FIG. 13 shows an exemplary wireless communication system 1300. The wireless communication system 1300 depicts one base station 1310 and one UE 1350 for sake of brevity. However, system 1300 can include one or more base stations and / or one or more UEs, where additional base stations and / or UEs can include exemplary base station 1310 and UE 1350 as described below. It should be understood that can be substantially the same or different. Further, the base station 1310 and / or UE 1350 may be configured to use the systems (FIGS. 1-7, 11-12, and 14-16) and / or methods described herein to facilitate wireless communication therebetween. (FIGS. 8-10) can be used.

  At base station 1310, traffic data for a number of data streams is provided from a data source 1312 to a transmit (TX) data processor 1314. According to an example, each data stream can be transmitted over a respective antenna. TX data processor 1314 formats, encodes, and interleaves the traffic data stream based on the particular encoding scheme selected for the data stream to provide encoded data.

  The coded data for each data stream can be multiplexed with pilot data using orthogonal frequency multiplexing (OFDM) techniques. Additionally or alternatively, the pilot symbols can be frequency multiplexed (FDM), time division multiplexed (TDM), or code division multiplexed (CDM). The pilot data is typically known data that is processed in a known manner and can be used at UE 1350 to estimate channel response. The multiplexed pilot and encoded data for each data stream is a specific modulation scheme (eg, two phase shift keying (BPSK), four phase shift keying (eg, selected) for that data stream to provide modulation symbols. QPSK), M-phase shift keying (M-PSK), M quadrature amplitude modulation (M-QAM), etc.). The data rate, coding, and modulation for each data stream can be determined by instructions performed or provided by processor 1330.

TX MIMO processor 1320, with respect to _{N T} transmitters (TMTR) 1322a~1322t, provides _{N T} modulation symbol streams. In various embodiments, TX MIMO processor 1320 applies beamforming weights to the symbols of the data stream and to the antenna from which the symbols are being transmitted.

Each transmitter 1322 receives and processes a respective symbol stream to provide one or more analog signals and further conditions the analog signal to provide a modulated signal suitable for transmission over a MIMO channel (eg, , Amplify, filter, and upconvert). Further, _NT modulated signals from transmitters 1322a through 1322t are transmitted to _NT antennas 1324a through 1324t, respectively.

At UE 1350, the transmitted modulated signals are received by _NR antennas 1352a through 1352r, and the received signals from each antenna 1352 are provided to respective receivers (RCVR) 1354a through 1354r.

RX data processor 1360 can demodulate, deinterleave, and decode each detected symbol stream to recover the traffic data for the data stream. The processing by RX data processor 1360 is complementary to that performed by TX MIMO processor 1320 and TX data processor 1314 at base station 1310.

  The processor 1370 can periodically determine which precoding matrix to use as described above. Further, processor 1370 can formulate a reverse link message comprising a matrix index portion and a rank value portion.

  The reverse link message can comprise various types of information regarding the communication link and / or the received data stream. The reverse link message is processed by a TX data processor 1338 that also receives traffic data for multiple data streams from data source 1336, modulated by modulator 1380, conditioned by transmitters 1354a-1354r, and base station 1310 can be returned.

  At base station 1310, the modulated signal from UE 1350 is received by antenna 1324, conditioned by receiver 1322, demodulated by demodulator 1340, and RX data processor to extract a reverse link message transmitted by UE 1350. Processed by 1342. Further, processor 1330 can process the extracted messages to determine which precoding matrix to use to determine beamforming weights.

  Processors 1330 and 1370 can direct (eg, control, coordinate, manage, etc.) operation at base station 1310 and UE 1350, respectively. Respective processors 1330 and 1370 can be associated with memory 1332 and 1372 that store program codes and data. Processors 1330 and 1370 can also perform computations to derive frequency and impulse response estimates for the uplink and downlink, respectively.

  With reference to FIG. 14, illustrated is a system 1400 that enables managing access control in a wireless communication environment. For example, system 1400 can reside within a UE. System 1400 is depicted as including functional blocks, which can be functional blocks that represent functions implemented by a processor, software, or combination thereof (eg, firmware). That should be understood. System 1400 includes a logical grouping 1402 of electronic components that can act in conjunction.
